It is possible that Kai's little bounce this AM was from where he went lower after +4. I'm thinking thats probably what it was but I am also wondering if maybe it's because of stress. I am dog sitting for my brother this weekend and he dropped his dog off late last night. And although my brother's dog wouldn't hurt Kai (she is 15 and almost completely blind so she can't even see him lol) Kai doesn't like strangers of any species in his house and i think it stress him out just a little when we have visitors.
